Are Lemons and Limes High in Potassium? (Revealed)

Both limes and lemons are very common citrus fruits. They are small, acidic, and very flavorful, making them great additions to various dishes as well as juices and smoothies. 

Lemons and limes provide you with a lot of important vitamins and minerals, including potassium. 

But, if you suffer from kidney disease, you know you have to limit your consumption of this mineral. So, are lemons and limes high in potassium?

Lemons and limes are low-potassium fruits, making them a safe addition to a low-potassium, kidney-friendly diet. They’re also easy to incorporate into many dishes and beverages, improving their nutritional value and adding more health benefits. 

As you can see, there are no reasons why you shouldn’t add some lemon and lime juice to your diet.

How much potassium is in lemon?

One whole lemon contains 80 mg of potassium. This isn’t a lot, especially considering that people don’t tend to eat whole lemons in one sitting. 

As a result, lemons make for a great addition to a low-potassium diet. For example, you can squeeze some lemon juice into cold water. 

This creates a delicious low-calorie and low-potassium drink that can help you stay hydrated.

One tablespoon of canned or bottled lemon juices contains 15.3 mg of potassium, while the same amount of fresh lemon juice provides you with 14.2 mg of potassium.

As you can see, the amount doesn’t differ much, so you can use both, depending on your preferences. 

Canned and bottled juice might be higher in sugar and contain preservatives, though, so keep that in mind. 

Some varieties may also contain a large amount of sodium, increasing your risk of high blood pressure and strokes.

How much potassium is in lime?

A whole lime contains 68.3 mg of potassium. It’s a slightly lower amount than that from lemons, but it’s mostly due to the fact that limes are generally smaller than lemons. 

Limes are still a great source of several important vitamins and minerals, but their taste is a bit more bitter. 

Regardless, limes can often be used as a replacement for lemons in cooking. The largest amount of nutrients is found in the pulp, so it might be best to slice up limes and add them to dishes that way.

One tablespoon of raw lime juice contains 18 mg of potassium, and the same serving of canned or bottled lime juice provides 16.5 mg of this mineral. 

So, just like lemon juice, you can safely drink it with some water to stay hydrated and load up on vitamins and beneficial plant compounds. 

Lime juice can also be added to teas, smoothies, and even meaty dishes, boosting their flavor.

Are lemons and limes healthy?

Both lemons and limes are rich in vitamin C. This micronutrient is very important for your body, as it promotes heart health, boosts your immune system, improves iron absorption, and keeps your skin healthy. 

Vitamin C is also responsible for maintaining your cartilages, bones, and teeth, as well as the growth, development, and repair of your tissues and cells. 

Since it’s a water-soluble nutrient, it’s important to get enough of it each day from a wide variety of foods and beverages.

Limes and lemons also contain a lot of powerful antioxidants. These compounds help flush out harmful free radicals from your body, preventing oxidative stress and damage to your cells. 

This lowers your risk of several chronic conditions, including diabetes, heart disease, and many types of cancer.

Antioxidants aren’t produced in your body, so it’s important to get enough antioxidant-rich foods from your diet, including lemons and limes.

Some studies also show that eating lemons and limes can improve your digestive health. Both of these citrus fruits contain a good dose of fiber, especially pectin. 

This type of fiber is insoluble and has many health benefits, which include slower digestion of sugars and starches, leading to lower blood sugar levels

As a result, eating pectin-rich foods can help prevent diabetes and other vascular issues. 

It’s worth noting, though, that those drinking lemon and lime juice are getting less fiber than those who eat the pulp, as that’s where it’s primarily found.

Eating and drinking limes and lemons and their juices can also improve your skin. Studies found that people who have a higher intake of vitamin C have a lower risk of wrinkles and dry skin as they age. 

This is beneficial for everyone who’s looking to improve their skin health through their diets. In addition, these fruits also contain lots of antioxidants, which can help prevent age-related skin changes and damage. 

The same antioxidants can also increase collagen production, an important protein for your skin.

Can you take in too much potassium from lemons and limes?

Lemons and limes are both low in potassium. As a result, it’s nearly impossible to take in too much of this mineral from just eating these fruits or drinking their juices. 

Most people add some lemon or lime juice to their foods and beverages, so they’re consuming less than the potassium from the whole fruit. 

This makes them good low-potassium fruits for those with kidney issues and potassium sensitivity.

While drinking too much lemon or lime juice is not likely to lead to a potassium overdose, both lemons and limes are acidic. 

They do have alkaline-forming properties once they’re digested and metabolized, but before that happens, they can irritate your esophagus and stomach, leading to inflammation and acid reflux symptoms. 

So, people dealing with these issues should consume lemon and lime juice in moderation, preferably mixed with a large jug of water for the best benefits.


Lemons and limes are low in potassium, which means that they can be safely consumed on low-potassium diets and by those with kidney issues. 

They’re also low in calories but high in flavor, other nutrients, and plant compounds. 

Because of that, they can contribute to good health and bring you other wonderful health benefits when consumed in moderation. 

The only people who should be careful with consuming lemons and limes are those with acid reflux, as too many of these fruits can worsen their symptoms.
